The most amazing...
...project I've led was the development of a recommendation system at Blinkit, boosting average order value by 10% and customer engagement for 500,000 daily users.
Work Experience
Senior Data Scientist
Redaptive
- Spearheaded the development of a scalable generative AI system for automatic summarization of sustainability reports using advanced NLP.
- Reduced manual work by 80% and saved 300 person-hours monthly through an interactive chat app by integrating retrieval-augmented generation and LLMs.
- Built an ML pipeline to estimate project costs for Redaptive, leveraging ensemble models and AWS Lambda for real-time vendor cost validation. Identified discrepancies and savings in 10% of estimates, resulting in more competitive project bids.
- Implemented an interactive Plotly Dash app to verify newly installed smart meters using meter timestream data.
Data Science Lead
Blinkit
- Introduced scalable product recommendations across the app to improve AOV by upselling and cross-selling products across 500,000 daily active users, resulting in a 10% AOV boost in the A/B (50/50) test.
- Deployed a gradient boosting-based ETA model for delivery service, enhancing delivery time accuracy by factoring in geospatial polygons and distance, resulting in increased customer satisfaction and a notable 4% improvement in the conversion rate.
- Spearheaded a nationwide periodic recommendations product launch.
Senior Data Scientist
Tokopedia
- Developed and implemented a scalable real-time bidding (RTB) system for sponsored ads, leveraging advanced ranking algorithms and cloud infrastructure to optimize ad placements, which resulted in a 2% increase in ad revenue.
- Engineered a keyword targeting tool to enhance product listing visibility and optimize ad performance by improving search hit rates. This led to a notable increase in ad revenue, driving higher engagement and profitability for the platform.
- Contributed to active learning pipeline development for NLP tasks.
Experience
Effortless SQL
I focused on refining prompts to enhance the precision and optimization of SQL queries, leading to improved data retrieval. I also developed reusable query templates by abstracting and substituting literals, which streamlined the process and significantly reduced the number of API calls, thus lowering associated LLM usage costs. The project also included fine-tuning LLMs on specific domain data to improve their contextual understanding and query accuracy, resulting in a more efficient and intelligent database querying system.
